ExpressionSet with all common genes in a mergeExpressionSet

Description

Given a mergeExpressionSet, this function returns a single ExpressionSet. Only genes common to all studies are included. Expression data for all studies sits side by side in the 'exprs' slot. The 'notes' slot is used for inormation about the study identity of each sample.

Usage

   intersection(x)

Arguments

Value

Returns an object of class ExpressionSet
